表姐 means older female cousin of a different surname. If surnames are always passed down via the father that implies an elder cousin who is either your mother’s sibling’s daughter or your father’s sister’s daughter.
It is hard to argue that detaining 1 million people for their beliefs[0] and then torturing them[1] is justifiable by cultural relativism. Or massacring people for that matter[2]. At that point you could argue for any atrocity.
It’s not rude it’s basic humanity. It’s not just completely reasonable to ask a government in charge of more than a billion people to please exercise basic humane standards, it’s morally atrocious to suggest otherwise. The Chinese government deserves all they criticism they get for what they have done and continue to do, and it’s arguable that we in the west deserve criticism for enabling them.
Most Americans just don't care. In a few years it will be as unpopular to talk about China's exploits as it is talking about Israel-Palestine. You can argue that Europeans don't care either, but at least the work culture and society is different enough from China to make the latter unappealing. Much less so for Americans.
I’m an undergrad right now preparing to take an exam for a course that was taught this way (Single Variable Calculus, https://youtube.com/channel/UCLzpR8AiHx9h_-yt2fAxd_A). Overall I felt like the course was better for being taught this way, and my classmates mostly think similarly. I think one key differences from what you’re describing though is that instead of periods to work on homework lectures were directed periods of applied learning where the professor gave us problems one by one and walked us through them when we got lost.
Overall I felt like this made the lectures more essential not less. In my other math lectures the professors mostly just explained the material in the textbook/notes that you could learn just as easily on your own. The applied learning style of the lectures for this course made each lecture unskippable if you really wanted to understand the material. The problems in the textbook didn’t come with any explanation for their solutions, and weren’t as similar to the problems on the tests and the problem sets as the problems in the lectures, so there was a lot of value lost if you missed a lecture.
For me personally, I prefer learning directly from the textbook so the videos were not that great, but the interactive lecture style is how I would want all of my future math courses to be taught, if I could choose.
Really it'd be hypocritical for them to support something they never previously supported just because of the president. The tech industry has been in favor of net neutrality for as long as it's been an issue i.e. far longer than the trump administration has been around.
